Title: Gene d'identification d'individus atteints de dysautonomie familiale
Inventor: SLAUGENHAUPT SUSAN
IPC: C12Q1/6883
Filed: 2002-01-07
Granted: 2015-11-24
Abstract: L'invention concerne des méthodes et des compostions utilisées pour détecter des mutations entraînant la dysautonomie familiale. La dysautonomie familiale (FD; syndrome de Riley-Day), une affection qui touche les personnes d'origine juive ashkénaze, constitue le groupe le mieux connu et le plus fréquent des neuropathies sensorielles congénitales et se caractérise par un dysfonctionnement des systèmes sensoriel et végétatif variable généralisé. Dans le passé, le gène de la FD, <I>DYS</I>, a été cartographié, sur une région 0,5 cM du chromosome 9q31 et on a démontré que la discrimination raciale est due à un effet fondateur, avec >99,5 % d'allèles malades partageant le même haplotype ancestral. Pour examiner la base moléculaire de la FD, la région candidate a été séquencée et clonée, et ses 5 gènes caractérisés. L'un de ceux-là, <I>IKBKAP</I>, contient deux mutations pouvant entraîner la FD. La mutation majeur d'haplotype se situe dans le site donneur d'épissage de l'intron 20. Cette mutation peut faire sauter l'exon 20 dans l'ARNm des patients atteints de FD, même s'il continue à exprimer des taux variables de messages de type sauvage de façon spécifique aux tissus. L'ARN isolé dans des lymphoblastes de patients est principalement du type sauvage, et seul le message effacé est visible dans l'ARN isolé du cerveau. La mutation associée à l'haplotype mineur chez quatre patients est une mutation faux-sens (R696P) dans l'exon 19 qui est censée disloquer un site de phosphorylation potentiel. Ces résultats indiquent que pratiquement tous les cas de FD sont provoqués par un défaut d'épissure inhabituel qui affiche une expression spécifique aux tissus; ils fournissent également une base pour le criblage rapide de transporteurs dans la population juive ashkénaze.

Granted: 2008-02-19
Abstract: A system for variable speed control of a plurality of motors under variable load demand is provided. The system includes a constant power source and a plurality of motors having electrical circuits with switches to connect with the constant power source. The system further includes a variable speed drive for driving each of the plurality of motors at variable speed, wherein each of the plurality of motors includes a switch to connect with the variable speed drive. Each of the plurality of motors is selectively electrically connected with the variable speed drive and the constant power source via the switches, for driving the each of the plurality of motors at one of variable and constant speed in response to load demands. To prevent short cycling of the motors under situations of increasing system demand, the control algorithm for the electrical switches provides hysteresis by overspeeding one of the motors before switching from variable speed mode to constant speed mode. Similarly, hysteresis is included in the control algorithm to prevent short cycling of the motors under situations of decreasing system demand.

Abstract: In this invention, a channel estimation value of data symbols of a data channel is calculated by weighting and averaging pilot symbols in a parallel time multiplexing method. Also, a channel estimation value of data symbols during each data symbol interval is calculated by dividing data symbols in a slot Into a plurality of data symbol intervals, selecting pilot symbols suitable for calculation of a channel estimation value of data symbols during each data symbol interval and weighting and averaging that pilot symbols. Also, a fading frequency is detected based on an inner product value of pilot symbols.    Weighting factors are changed based on the detected fading frequency. Also, a channel estimation value is calculated by weighting and averaging pilot signals using a plurality of weighting sequences. The calculated channel estimation value is used to demodulate received data. The output data with the highest quality is selected by judging reliability of these plurality of demodulated data. It is also possible to select some weighting sequences based on the result of the reliability judgment of the demodulated data for predetermined period of time. In this case, after the selection, demodulation is performed by using these selected weighting sequences only.
